Application led December 4, 1916. Serial No. 134,873.

To @ZZ whom t may concern:

Be it known that l, CHARLES. E. BATES, a citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Armor for Pneumatic Tires, oli' which the iollowing is a specification.

This invention relates to pneumatic tires and more particularly to armors for this class of tires and particularlyT to an armored interliner and has for its object the production of a device of this class that will present at all times a metallic armored surface.

Another obj ect is to provide an interliner of this class that willfpresent asmooth nonchaing `face to the inner tube.

A still further object is to produce a device of this class having an entirely new and novel form of armor that will be light and durable.

Other objects and advantages such as simplicity, durability, cheapness in manufacture and the general improvement of the art will be fully brought out in the following specilication and illustrated in the accompanying drawings in which:

Figure 1 is a top plan view ot my device partly broken away to show the diii'erent layers of construction,

Fig. 2 is a bottom plan view of a portion of my device,

Fig. 3 is a cross sectional view,

Fig. 4 is a perspective view ot my device as a whole.

Fig. 5 is a view showing the construction of the bottom row ot disks.

Fig. 6 is a view of the special designed rivet used in securing the two top layers of disks in place.

Referring more particularly to the drawings the numeral 1 desi ates the base of my interliner which is pre erably leather. rlFhe base 1 has a plurality of rows of flat disks 2 permanently secured to its surface. '.lhe

disks 2 are spaced apart and in staggered relation to each other.

A plurality of rows of substantially star shaped spaces 3 are left between the disks 2. A plurality of other disks 4 slightly conn cave, are mounted in the alternating rows of spaces 3, the disks 4 being oi such size that their edges touch.

A still other plurality of disks 5 of the same size and shape as the disks 4 are mounted in the remaining rows of spaces 3.

The disks 4 and 5 are loosely mounted on rivets 6 which have heads on both ends thus allowing flexibility.

A covering 7 is secured to the base 1 on the opposite side from the disks thus presenting a smooth non-chafing surface to the inner tube.

It will be readily seen that by my construction the inner liner is clearly flexible and that the point of the base directly beneath the point where the edges oi the disks 5 touch and the edges of the disks 4 touch is protected by the disks 2 which are flush to and secured to the base 1.

It will also be apparent that the disks do not impair the flexibility as they are loosely mounted on the rivets 6 and do not destroy the flexibility of the flexible base, and still present a solid or continuous metallic surface.

Having thus described my invention what l claim is:

1. An armored inner liner for pneumatic tires comprising a base, a plurality of disks spaced apart and in staggered relation to each other rigidly secured to said base, other disks loosely mounted on rivets in said base between said first-mentioned disks, said second-named disks overlying said first-named disks, a third set oi disks secured loosely on rivets in said base between said secondnamed disks and extending over the spaces between said second-named disks, and means secured to the inner side of said base for preventing chafing of an inner tube.

2. An inner liner for pneumatic tires comprising a base of liexible material, a plurality of metallic disks rigidly secured to said base in longitudinal rows, each of said rows being in staggered relation to the adjoining rows, thereby leaving longitudinal rows of substantially star-shaped spaces between said disks, a second plurality of rnetallic disks of greater size than said iirstnamed disks and loosely mounted on rivets secured in alternating rows of said spaces second-named disks, and a flexible cover and adapted to overlie said first-named member secured to the under side of said disks7 a third plurality of disks of the saine base to prevent cheng of an inner tube.

size 'as said second named disks`- loosely ln testimony whereof I hereto aiix my 10 mounted on rivets secured' in the remaining signature.

roWs of spaces and adapted to overlie said. CHAS. E. BATES.
